For anyone who hasn't spoken to me before the answer is yes I am crazy.
Now thats out of the way here goes. For those of you who don't have a big garden to install a spring pole here is my solution for a cheap removable spring pole, the only disadvantages would be the dog only has 180- degrees and ideally it would have to be kept low (depending how much you value your doors).
Buy your slef a cheap set of these
a set with material handles would be best and make sure you get the door attachment with what ever set you buy attach your dogs favourite rag toy to the rubber band, attach it to the door and away you go.
Sorry for the low quality pics but she wouldn't stay still.
